Product Overview
The GE IC693BEM320E I/O Link Interface Module is a communication module designed for GE Fanuc Series 90-30 programmable logic controller systems. It provides an interface between a Series 90-30 PLC and a FANUC I/O Link network, allowing the PLC to exchange input and output data with compatible industrial control equipment.
The module is configured as an I/O Link slave. It can communicate with an I/O Link master in a FANUC CNC system or another compatible controller. This arrangement allows the Series 90-30 PLC to participate in a distributed control architecture in which data is exchanged between different automation devices.
The IC693BEM320E supports selectable 32-point or 64-point I/O configurations. The configuration is selected through a jumper inside the module, according to the system installation requirements. This allows the module to be adapted to different I/O data requirements within a compatible I/O Link system.
As part of the Series 90-30 PLC platform, the IC693BEM320E is suitable for industrial installations that need communication between PLC-based control equipment and FANUC automation systems. Typical applications include CNC machine integration, manufacturing equipment, and coordinated production systems.
The IC693BEM320E should not be confused with the IC693BEM321. Although both modules belong to the Series 90-30 I/O Link product family, the IC693BEM320E functions as a slave, while the IC693BEM321 is designed for master applications.

Function and Working Principle
The primary function of the IC693BEM320E is to provide a communication interface between a Series 90-30 PLC and a FANUC I/O Link master. It allows the PLC to exchange configured I/O data with the connected system.
1. FANUC I/O Link Communication
FANUC I/O Link is a serial communication system used to exchange I/O information between compatible industrial controllers and devices.
In an integrated automation system, the master device manages the communication process, while the IC693BEM320E operates as a slave. The module receives and transfers the configured I/O information through the I/O Link connection.
This arrangement allows signals associated with the Series 90-30 PLC to participate in the wider CNC or machine-control process.
2. Slave Device Operation
The IC693BEM320E is specifically designed for slave operation. It does not serve as the I/O Link master in the system.
A typical configuration may include a FANUC CNC controller or another compatible master device, the IC693BEM320E installed in a Series 90-30 PLC rack, and the associated PLC program.
The master coordinates the I/O Link communication, while the slave module provides the configured I/O data interface. This makes it possible for the PLC and CNC equipment to exchange machine status and control information.
3. Selectable I/O Capacity
The module supports two I/O configurations: 32 points and 64 points.
The required configuration is selected using a jumper inside the module. The selected setting must correspond to the intended I/O arrangement and the configuration of the connected master system.
During installation or replacement, engineers should verify the jumper position before commissioning. An incorrect setting may cause the I/O data arrangement to differ from the system configuration.
4. PLC Backplane Communication
The IC693BEM320E is installed in a compatible Series 90-30 PLC rack. It uses the PLC backplane for communication with the local controller and receives its operating power from the rack.
Its internal power consumption is approximately 205 mA at 5 V DC. The rack power budget must therefore account for this module together with the CPU and other installed modules.
5. Data Exchange Between Control Devices
The module supports communication between the Series 90-30 PLC and the I/O Link master. Depending on the machine configuration, exchanged information may represent machine commands, operating states, interlock signals, and other configured I/O data.
The exact meaning of each signal is determined by the PLC program, CNC configuration, and I/O assignment.
Role in Industrial Control Systems
The IC693BEM320E can serve as a communication interface in industrial systems where Series 90-30 PLC equipment must exchange I/O information with FANUC CNC or other compatible I/O Link systems.
PLC and CNC Integration
In CNC-based manufacturing, the CNC controller manages machine operations such as machining sequences and motion-related functions. A PLC can handle auxiliary machine logic, including interlocks, operating conditions, and peripheral equipment.
The IC693BEM320E provides an I/O Link connection that allows the Series 90-30 PLC to participate in this coordinated control architecture.
Machine Status Exchange
Industrial machines often need to exchange operating information between different control devices. Examples include machine-ready signals, cycle status, start permissions, and equipment fault indications.
The I/O Link interface supports the configured exchange of these signals between the PLC and the master system.
Distributed Control Architecture
In a distributed automation arrangement, different controllers manage separate parts of a machine or production process. The I/O Link connection allows the Series 90-30 PLC to communicate with compatible equipment without requiring every signal to be individually wired to a single central controller.
The actual system design must follow the supported I/O Link configuration and communication limits.
Industrial Applications
1. CNC Machine Integration
The IC693BEM320E can be used in systems where a GE Fanuc Series 90-30 PLC needs to exchange I/O data with a FANUC CNC controller.
This arrangement can support coordination between CNC operations and auxiliary machine functions.
2. Automated Manufacturing Equipment
Manufacturing equipment often combines PLC control with specialized machine controllers. The module can provide the I/O Link interface required for communication between compatible devices.
3. Machine Tool Control Systems
Machine tools may contain CNC controllers, PLC-controlled auxiliary equipment, safety interlocks, and peripheral devices.
The IC693BEM320E can help integrate the Series 90-30 PLC into a compatible I/O Link architecture for exchanging configured machine signals.
4. Production Line Coordination
In production environments, multiple control devices may need to exchange machine status and operating commands. The module can support this communication where the system uses FANUC I/O Link.
5. Legacy Automation Maintenance
Many industrial facilities continue to operate established Series 90-30 PLC installations. The IC693BEM320E may be required when maintaining existing CNC and PLC communication arrangements.
For replacement projects, matching the exact hardware revision and I/O configuration is important to maintain the original system behavior.
Installation and System Integration
1. Verify PLC Compatibility
Before installation, confirm that the PLC rack is compatible with the IC693BEM320E and that the system configuration supports the required I/O Link functionality.
Check the CPU, baseplate, installed modules, and available rack power capacity.
2. Check the I/O Link Configuration
The IC693BEM320E operates as a slave device. Confirm that the connected master supports the required FANUC I/O Link configuration.
Do not substitute a master module for this slave module without reviewing the system architecture.
3. Set the I/O Configuration Jumper
Select either the 32-point or 64-point configuration according to the system requirements.
The jumper is located inside the module. Follow the applicable installation documentation and ensure the module is safely isolated before opening or changing its configuration.
4. Check Rack Power Consumption
The module consumes approximately 205 mA from the 5 V DC backplane supply.
Calculate the total current consumption of all installed modules and confirm that it remains within the baseplate power supply’s available capacity.
5. Connect the Communication Wiring
Connect the I/O Link interface according to the FANUC I/O Link wiring requirements. Verify connector assignments, cable specifications, grounding, and communication topology.
Incorrect wiring or an incompatible connection arrangement may prevent the module from communicating with the master device.
6. Configure the PLC Program
The PLC hardware configuration and application program must correspond to the selected I/O point arrangement.
Verify the configured input and output assignments, signal direction, and data mapping before starting the machine.
7. Perform Commissioning Tests
After installation, verify module status indicators and confirm that the master and slave devices establish communication.
Test the configured I/O signals individually, including machine status, control commands, and interlock information. Confirm that the PLC program responds correctly before returning the equipment to production.
